Grids and Time Zones: ways of describing where things are
GEOGRAPHY - study of where things are found on Earths surface and the reasons for the locations
- Where are people and activities found on Earth?
- Why are they found there?
MAP - two-dimensional or flat surface model of Earths surface
CARTOGRAPHY - art & science of map making
Maps Purposes
- As a reference tool to identify an objects absolute and relative location
- As a communications tool to convey the distribution of human activities or physical features
ABSOLUTE LOCATION: Position as expressed in degrees, minutes, and seconds of latitude(North or South of the equator) and longitude(East or West of Prime Meridian)
RELATIVE LOCATION: regional position or situation of a place relative to position of other places
LATITUDE - geographic coordinate that specifies the north-south position of a point on Earths surface (measured by invisible lines parallel to equator
Significant Parallels
Arctic Circle
Tropic of Cancer
Equator
Tropic of Capricorn
Antarctic Circle
LONGITUDE - geographic coordinate that specifies the east-west position on a point (measured by imaginary lines; runs through poles)
- Prime Meridian passes through Greenwich, England, given 0 degree longitude
- Measures degrees east or west from Prime Meridian
